The Mont-Saint-Michel abbey is divided in two parts: the church-abbey and the "Merveille". The "Merveille" was the monk living area. Seen from outside, it has a gothic front, on the North side, has three levels and was built over 25 years.
The "Merveille" can be subdivided into two parts: the East and the West sides. The East side was built first (from 1211 to 1218)
